CAN-OPENER.

Specification of Letters Patent.

Patented Mar. 9, 1915.

Application filed flctober 3, 1914. Serial No. 86%,913.

To all whom it may concern Be it known that I, JOHN P. WALSH, a citizenof the United States, residing at New York, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Can-0p eners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to can openers, and one of the principal objectsof the invention is to provide a can opener of simple construction whichwill operate quickly and which will readily cut out the top or head of asquare or round can by a single out without rotating the cutters, saidcutters being connected to the operating screw by a ball and socketjoint, so that the screw will turn without rotating the cutter.

Another object of the invention is to provide a cutter of either roundor square form in which the cutting blades are angular in form having aninclined cutting edge and a vertical rear edge, so that when the cutteris forced down into the top of a can, the entire top or a continuousopening will be formed therein permitting the removal of the portion cutby the separate cutting points.

The foregoing and other objects may be attained by means of theconstruction illus trated in the accompanying drawing, in which,

Figure 1 is a vertical sectional view of a can opener made in accordancewith this invention, the threaded plunger or shaft being shown inelevation, Fig. 2 is a detail perspective view of the cutter removedfrom its shaft or plunger, Fig. 3 is a view of the lower end of theplunger or threaded shaft and showing the ball member of the cuttersecured to the socket, and the cutter being broken away at oppositesides of the ball, and Fig. 4 is a top plan view of a cutter of circularform.

Referring to the drawing, the numeral 1 designates a shelf projectingfrom a wall or suitable support 2 and connected to the shelf 1 is abracket 3, said bracket having an arm 1 which projects underneath theshelf and is secured thereto by means of suitable bolts 5. The bracket 3is provided with a horizontal arm 6 at its upper end, said arm beingprovided with a screw threaded bore 7. Fitted into the threaded bore 7is a shaft or plunger 8 provided with a cross handle 9 at its upper end.The shaft or plunger 8 at its lower end is provided with a cross headconsisting of two separable members 10 and 11 secured together by meansof bolts 12 extending through both members and said members are providedwith semi spherical sockets 13, so that when they are both broughttogether, the socket is round to accommodate a ball member 14 formed onthe cutter. The cutter comprises the rectangular frame 15 having crossedbrace bars 16, and located centrally of the cross bars 16 is the ball 14which is adapted to be connected to the socket 13 of the plunger orshaft 8. Projecting downward from the rectangular frame 15 are thecutting teeth or blades 17 said blades each having an inclined cuttingedge 18 and an unsharpened vertical back edge 19. As shown in Fig. 41the cutter may be round instead of rectangular as shown in Figs. 1 and2.

The operation of the invention may be briefly described as follows: Acan a is placed upon the shelf 1, and the shaft or -plunger 8 is rotatedto bring the points of the cutters or blades in contact with the top ofthe can, and by further rotation of the shaft 8 the top is cut out ofthe can and the opposite rotation of the plunger or shaft 8 will carrythe cutter out of the way. With this form of cutter, the contents of thecan are not disturbed since it is held upright and the top is cut outwithout rotation of the cutter to disturb the contents of the can. Theform of teeth of the cutter insures the removal of the entire piece ofmetal from the can, said piece conforming to the contour of the cutterframe.

Changes in the details of construction may be resorted to withoutdeparting from the spirit and scope of the invention as defined in theclaims.

What is claimed is l. A can opener comprising a bracket having ahorizontal arm provided with a threaded bore therein, a threaded shaftor plunger mounted in the bore and provided with a handle, said shafthaving separable members provided with a ball socket at one end, acutter comprising a frame having a ball thereon to engage said socket,said frame being provided with projecting cutters or b ades, e h havingan inclined cutjoint, whereby the plunger may be moved 10 toward a canithout rotating-the cutter.
